Lean Six Sigma Yellow Belt CertificationAcuity Institute’s Lean Six Sigma Yellow Belt course has been designed to teach Lean Six Sigma fundamentals and its application. It is intended for improvement project team members.  Yellow Belt team members form an important part of a mature Lean Six Sigma deployment.  As Black Belts and Green Belts begin projects, they will need team members.  In this course students are trained and tested on their understanding and ability to apply the tools and techniques of various elements of the Lean Six Sigma methodology. Our aim is to develop the most competent Yellow Belts capable of taking on difficult challenges with ease as Lean Six Sigma team members.

Training is conducted online and uses a multi-media format that includes audio by Lean Six Sigma experts, examples of successful performance improvement, interactive simulations and quizzes, and the most current and robust tools and techniques available.  The course is “self-paced” and can be accessed at any time – and – anywhere, which provides the most flexibility in completing the course.  On average, students complete the Lean Six Sigma Yellow Belt training course in 30 hours (average completion time, actual time may vary).

Acuity Institute’s Lean Six Sigma Yellow Belt course is one the most comprehensive in the world.  We recommend this course to Project Team Members, Department Leaders and anyone who is interested in taking their Lean Six Sigma knowledge to a deeper level (and not as deep as a Green Belt or Black Belt).

Key Outcomes (on completion of this course, students will be able to…)

  • Understand Lean Six Sigma and the DMAIC methodology
  • Understand their role in a successful Lean Six Sigma deployment
  • Properly participate on Lean Six Sigma projects
  • Apply methods learned in the DMAIC process to business issues

Acuity Institute wants the learning experience to be as supportive and engaging as possible, we are here to help you succeed.  We understand the importance of having a place to ask questions to the experts about tools and techniques, exercises, project work or general technical support.  During training, students can submit questions to instructors through Acuity Institute’s Student Center.  Responses are provided to student questions in one business day or less.  If questions and/or answers are complex, an Acuity Institute instructor will schedule a one-on-one phone meeting with the student to review the question/answer.


At Acuity Institute, we recognize that not every individual has the opportunity to complete an actual Lean Six Sigma project while completing training; therefore, we have created a real world simulated project that takes students from the beginning to the end of a problem and solution. The simulated project helps to build the student’s understanding of the concepts taught in training and provides practical application of the tools.  Students complete the course better prepared to apply what they have learned in the real world.

The simulation is based on a hypothetical company that faces many of the same problems companies are dealing with today.  The simulation is designed to illustrate the entire business improvement effort through every phase of the Lean Six Sigma DMAIC methodology.  Students complete 11 challenging exercises which build on previously learned tools and concepts taught in training.  When complete, students have a significant perspective on what true business improvement means and a tangible “project story” that they can utilize throughout their process improvement journey. 

There is no comparison of this simulation in the marketplace today.  No other Lean Six Sigma service provider offers a comprehensive project simulation such as ours.


Acuity Institute’s Lean Six Sigma Yellow Belt Certification Exam is the standard for Yellow Belt Certification.  Upon completing training, students will be required to achieve a passing mark of 80% or higher on the exam.  The exam is intended to validate student proficiency with Lean Six Sigma tools and techniques.  The following highlights the Lean Six Sigma Yellow Belt Certification Exam.

  • The Lean Six Sigma Yellow Belt Certification Exam is included in the program.  Students will have 1 attempt to successfully pass the exam (80% or higher).  If a student does not pass the exam they will be charged a fee of $25 if they choose to retake the exam.  Upon submitting the retake fee, Acuity Institute will provide areas in the course for the student to review prior to the next exam attempt.
  • The exam is administered online.  Students will need to have an active internet connection to complete the exam.
  • The exam is open book.  Students may use any reference materials to complete the exam (training manuals, project materials, statistics books, etc.).

Through our experiences we have assembled the Lean Six Sigma Toolkit.  The toolkit assists Lean Six Sigma practitioners in keeping focused on their project work and not creating “templates”.  The toolkit includes 17 templates from the Lean Six Sigma DMAIC methodology.  For ease of use, the templates can be downloaded directly to your computer.  The templates are in common formats (MS Word, MS Excel or MS PowerPoint).  Included templates: Data Collection Plan, DMAIC Tollgate Presentation, FMEA, Implementation Plan – Detailed, Implementation Plan – High Level, Process Monitoring Plan, Process Value Analysis, Project Charter, Project Storyboard, Quick Win Identification, Response Plan, Sigma Calculator, SIPOC, Solutions Selection Matrix, Standardized Procedures, Team Meeting Agenda, and Team Profile.
